YDSE: Fringe Width & Fringe Positions

A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is

Show answer and solution

Answer: (d)

With two parallel slits, each point of equal path difference lies along a line parallel to the slits.
So fringes on the screen are straight bands.
So the answer is (d) straight line.
